Evaluation Of Rhizobium And Mycorrhiza Interactions In Sustainable Maize(Zea Maysl.)And Soyabean(Glycine Maxl.) Production

ABSTRACT Maize and soyabean are among the staples in the world. Their sustainable production through the use of synthetic fertilizer causes soil degradation and ground water contamination. An alternative means of boosting and sustaining the production of these staples through the use of rhizobium and mycorrhiza have been reported but there are contradictory reports on interactions between the two organisms. Therefore, the objective of this study was to assess the influence ofRhizobium japoni...

Plant traits and drought tolerance in the Savanna: A Kruger National Park case study

Abstract One of the central goals of plant ecology is to understand the factors that control the local distribution of plant species and thus the composition of communities. The aim of this study is to determine plant functional traits that can be associated with drought tolerance/avoidance and to test whether wood density is a good indicator of drought tolerance. The study was carried out in Kruger National Park in the month of June. A number of plant traits including wood density, leaf thic...

Occurrence, Variability And Management Of Ralstonia Solanacearum In Potato Production Systems In Kenya

ABSTRACT Production of potato (Solanum tuberosum L.) in Kenya is constrained by many biotic, abiotic and socio-economic factors. Among the biotic constraints, bacterial wilt, caused by Ralstonia solanacearum (Yabuuchi et al., 1995) presents major management difficulties. Attempts to combat the disease have been difficult due to the complex heterogeneous genetic make-up of the pathogen, comprising different races and biovars, its survival mechanisms and its large number of hosts, including wee...

Comparative Study of the Growth and Yield of Three Cultivated Pleurotus Species on Selected Tropical Trees Sawdusts

ABSTRACT The quest to boost dietary protein production from readily available and affordable sources is ever increasing in developing countries. The indigenous edible Pleurotus species (oyster mushrooms), which grow naturally on wood wastes, are potential protein supplements. However, little information is available on the usage of selected tropical trees for optimum mushroom cultivation. Therefore, this research was designed to investigate the growth and yield of oyster mushrooms on sawdust...

Abstract Lippia javanica (Burm. F.) Spreng occurs naturally in eastern, central and southern Africa. It has widely been used as herbal tea, for ethnomedicinal applications and as a botanical pesticide. Lippia javanica species exhibit great morphological and chemical variations which are notable across a number of natural populations. Differences in morphological taxonomy on important characters such as peduncle length and number of inflorescence per axil have been reported which has led to th...

Effects Of Management And Rainfall Simulation On Soil Respiration And Soil Carbon Store In A Moist Kenyan Savanna, Ruma Lambwe Valley

ABSTRACT The demand for agricultural land is driving the conversion of moist Kenyan savannah into agroecosystems (grazing fields and croplands) and together with altered rainfall patterns, is likely modifying soil moisture, soil respiration and carbon store in the ecosystem. Nevertheless, the carbon dynamics of moist savannas plus of the converted ecosystems are poorly understood yet planning for sustainable use of the ecosystem need to be based on scientific knowledge. While previous studie...
